I think that the software is set-up such that in a topic's title any letter that is not preceded by a space will be displayed as a small case letter once it is entered. I believe that the reason for this is to prevent titles that are all capital letters and I believe the reason for this avoidance of all capitals is because CM feels that all capitals seem to show too much of one or another kind of aggression or vehemence and that this will upset some of the viewers.

I think that all capitals should be allowed. I think that at most a very few members will actually wilt at the sight of a lower-caseless title. I think that coming across "Jrr Tolkien", "J.r.r. Tolkien" or "god" is more disturbing.
